在自定义Cell TableView中选择了哪个TextField？

Question

使用Swift4，iOS11.1，Xcode9.1，

从tableView做一个segue，我试着找出如何检测用户触摸的两个TextFields（在我的自定义单元格中）中的哪一个。我的自定义Cell tableView有两个TextField，如下图所示：

到目前为止，这是我的代码：

// tableView delegation-method:
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let cell = tableView.cellForRow(at: indexPath)
    self.performSegue(withIdentifier: "goToMyNextVC", sender: cell)
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

    if segue.identifier == "goToMyNextVC" {

        let newVC = segue.destination as! MyNextViewController

        let indexPath = self.tableView.indexPathForSelectedRow
        print(indexPath?.row)  // !!!!!! The cell-row is correct

        let cell = sender as! MyCustomTableViewCell
        newVC.someTextProperty1 = cell.firstTextFiled.text!  // works well
        newVC.someTextProperty2 = cell.secondTextFiled.text!  // works well

        // !!!! BUT HOW DO I GET WHICH OF THE TWO TEXTFIELDS WAS TOUCHED ?????????

        // newVC.someTextProperty3 = ??????? text of touched TextField ???????

    }
}

任何帮助表示赞赏！

Answer 1

您应该在MyCustomTableViewCell类的textField中注册一个tap事件，然后将哪个textField分配回viewController。

但更简单的解决方案就是在两个不同的文本字段中使用两个不同的单元格。

Answer 2

我找到了一个解决方案（以某种方式由Demosthese暗示触发）：

1。）在自定义单元格内部：调用单元格配置方法（分配每个textField的标签（或者我的情况下现在的标签......）

func configureCell(tag: Int) {

    // assign tag (later used to expand / collapse the right cell)
    self.fristTextField.tag = 1
    self.secondTextField.tag = 2

    self.firstTextField.isUserInteractionEnabled = true
    self.secondTextField.isUserInteractionEnabled = true
}

自定义单元格内的

1. ：定义触摸标签taht的touchesBegan方法，并指定＆＃34; tagNrTouched＆＃34; -property

   override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
   
       super.touchesBegan(touches, with: event)
       let touch: UITouch = touches.first!
   
       if (touch.view?.tag == self.firstTextField.tag) {
           self.tagNrTouched = 1
       } else if (touch.view?.tag == self.secondTextField.tag) {
            self.tagNrTouched = 2
       }
   }
   

2. 在tableView中，在segue＆＃39;之前对此属性作出反应：

   // tableView delegation-method:
   func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) 
   {
       let cell = tableView.cellForRow(at: indexPath)
       self.performSegue(withIdentifier: "goToMyNextVC", sender: cell)
   }
   
   override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
   
       if segue.identifier == "goToMyNextVC" {
   
           let newVC = segue.destination as! MyNextViewController
   
           let indexPath = self.tableView.indexPathForSelectedRow
           print(indexPath?.row)  // !!!!!! The cell-row is correct
   
           let cell = sender as! MyCustomTableViewCell
           newVC.someTextProperty1 = cell.firstTextFiled.text!  // works well
           newVC.someTextProperty2 = cell.secondTextFiled.text!  // works well
   
           // HERE IS THE FINAL SOLUTION: REACTING ACCORDING TO THE TAG-NR
           if (cell.tagNrTouched == 1) {
                textSearchVC.searchText = cell.firstTextField.text!
           } else if (cell.tagNrTouched == 2) {
                textSearchVC.searchText = cell.secondTextField.text!
           }
       }
   }
